摘要
該設(shè)計(jì)是有單片微機(jī)控制的火災(zāi)自動(dòng)探測(cè)報(bào)警控制器，將煙傳感器及溫度傳感器接入單片微機(jī)，經(jīng)微機(jī)運(yùn)算和邏輯判斷，經(jīng)專用聲光報(bào)警集成電路來(lái)進(jìn)行火災(zāi)報(bào)警，異常（煙感，溫感其中之一動(dòng)作）報(bào)警，故障報(bào)警及引爆控制，消防一體化。由于單片機(jī)集成度較高，故該設(shè)計(jì)具有結(jié)構(gòu)簡(jiǎn)單，可靠性好，成本低等優(yōu)點(diǎn)。
由于現(xiàn)代建筑事業(yè)的快速發(fā)展，在現(xiàn)代建筑中要求具有火災(zāi)報(bào)警以至自動(dòng)消防系統(tǒng)，基于此目的,采用了AT89C51單片機(jī)以及8279芯片等進(jìn)行設(shè)計(jì),大大提高了系統(tǒng)的智能化和反應(yīng)速度。且本設(shè)計(jì)可同時(shí)用于監(jiān)測(cè)多個(gè)區(qū)域,其工作原理與本文所介紹內(nèi)容基本相同。
由于本設(shè)計(jì)所針對(duì)的場(chǎng)合的原因,所以對(duì)滅火劑的選擇有非常嚴(yán)格的要求,即能夠在噴放以后迅速接近火源并把其與空氣隔絕,達(dá)到滅火的目的, 七氟丙烷就是很好的滅火劑。

monitoring system of intellectual fire
Abstract
This design has the fire automatic-detection which the monolithic microcomputer controls to report to the police the controller, turns on the smoke sensor and the temperature sensor the monolithic microcomputer, after microcomputer operation and logical judgement, Reports to the police the integrated circuit after the special-purpose acousto-optics to carry on the fire to report to the police, exceptionally (smoke feeling, the warm feeling one of them movement) reports to the police, the breakdown reports to the police and the ignition control, the fire integration. Because monolithic integrated circuit integration rate higher, therefore this design has the structure simply, reliability good, the cost is low and so on the merit.
As a result of the modern architecture enterprise fast development, the request has the fire in the modern architecture to report to the police down to the automatic fire prevention system, based on this goal, has used the AT89C51 monolithic integrated circuit as well as 8,279 chips and so on carries on the design, greatly enhanced the system intellectualization and the reaction rate. Also this design may simultaneously use in to monitor many regions, its principle of work and this article introduced the content basic is same.
Because this design aims at situation reason, therefore has the extremely strict request to the fire-extinguishing choice, namely will be able to spurt later rapidly to approach the fire hazard and it with the air isolation, achieved the fire fighting the goal, seven propyl fluoride will be the very good fire-extinguishing.
Keywords: AT89C51 monolithic integrated circuit;8,279chips ;The fire reports

前 言
隨著電子技術(shù)的飛速發(fā)展，各類分立電子元器件已及其所構(gòu)成的相關(guān)功能單元已逐漸被功能更強(qiáng)大，性能更穩(wěn)定，使用更方便的集成電路所取代。由集成電路構(gòu)成的各種自動(dòng)控制，自動(dòng)測(cè)量，自動(dòng)顯示電路遍及各種電子產(chǎn)品和設(shè)備，單片微型計(jì)算機(jī)簡(jiǎn)稱為單片機(jī)，又稱為微控制器，是微型計(jì)算機(jī)的一個(gè)重要分支。單片機(jī)是上個(gè)世紀(jì)70年代中期發(fā)展起來(lái)的一種大規(guī)模集成電路芯片，是集CPU、RAM、ROM、I/O接口和中斷系統(tǒng)于同一個(gè)硅片的器件。80年代以來(lái)，單片機(jī)發(fā)展迅速，各類新產(chǎn)品不斷涌現(xiàn)，出現(xiàn)了許多高性能新型機(jī)種，現(xiàn)已成為自動(dòng)化和各類控制領(lǐng)域的支柱產(chǎn)業(yè)之一。
本設(shè)計(jì)為基于單片機(jī)的火災(zāi)報(bào)警系統(tǒng)，用于各類建筑中進(jìn)行火災(zāi)探測(cè)和報(bào)警。它以Intel公司的MCS-51系列單片機(jī)AT89C51為核心，采用煙傳感器和溫度傳感器對(duì)異常狀況進(jìn)行多角度監(jiān)測(cè)，通過(guò)專用的聲光報(bào)警系統(tǒng)進(jìn)行報(bào)警，接口電路來(lái)進(jìn)行一系列災(zāi)后動(dòng)作。
